It is shown that, contrary to what is normally expected, it is possible to have angular-momentum effects on the geometry of space-time at the laboratory scale, much bigger than the purely Newtonian effects. This is due to the fact that the ratio between the angular momentum of a body and its mass, expressed as a length, is easily greater than the mass itself, again expressed as a length.
